To' '(ZZotJ'UO'm'/fmcyl concern?? i Be it known that I, Josnri-r "fiorentini,l a subject of the'King of GreatBriftain, residing at lfligliltiveig inl theft-evince of Allbeita and Dominion# of` @anafdag have' in@ rented certain new and` useful Improves* ments inf Harness-Sewing Macliines;l` of which the" following is a sp/ecification My invention" relatesto1 improvements in harness sewing machines' wherein itis custon'iar-y to channel the leather 'ont theunder sidethereof wheii inthe act'of stitching: the severalE` parte' togfether` inl order that the channel may' afterward bei utili-'led to coverv the stitches on one" side of the' articlebeing stitched.

ihn object of my invention to' prodiice a \channeling-l mechanism which is adjust-n able to' different depths of channelsiy A further' object yofmy invention is to afford facilities for adjustment of the' clranL ncler by vafryin"g` the exposure' ofthe knife' while the machine in actualA operation A furtherobjectl of my invention lis to provide meansfor entirely withdrawing the channcler from its operative position whenV desirable without the necessity of stopping the machine: l

A still' further object of my linvention is tofk'irrange' the cutting mechanism fof the channeler below the surface `of the base plate, thus alloi'ving a perfectlwr` smooth upper surface for the'plate,v and to so directy the channeler knife i'pbortioiij that it may be easily removed and replaced by newly sharpened knife portions;

A ihiindicates basep'l'ate which as shown iir Fig- 5f 1sl attached to the stitching Ina-` chihe 1nsuch a manne-r as to bring? the' elongated slot a directly beneath the presser foot- B of the stitcl'li-ngf machine,

which presser" foot operates in the usuali manner.

Arranged inl advance ofthe presser foot Bi and needle is a clianneli cutter t whichv is adapted to eil-'ect'` a channel; on the under side ofthe leather being' stitchecll prior to its passing between thel presser" foot B and plate* Ai.A This channel! 'cutter' is carriedV by a rock shaft b which is arranged lonlgitudinally of the 'plate fr and trirnsversely of the stitching.` machine; Thisr`4 roc-li: ,shaftb is suitably journaled in ther plate by' rie--v "lehe rockA shaft is' pieferably made' inV two parts as clearly shown in Fig. 2', which willY permit ofthe replacement of the chan'-y nel cutter without affecting the cutter adlrusting mechanisnr. c' c represents the adf-y jfustinfg screws whichv are adapted to bear against the' `outer ends of the roch shaft; thereby providing means for laterally afd- ]justi'ng' the channely cutter;

Arranged at tli'e ifnn'er end'l of the plate A.`

is' a horizontal sliding block e which is carried* a horizontal gui'de rod it. rllhis block c is connected through the medium to the outer end of the rock shaft Z9.

The horizontal movement of the bloclr e is effected by a thumb screw a which is rotatably secured `to the plate A having its screw threaded end received within the threaded portion of the block e. It is apparent that with the rotation of the adjusting screw a the cutter knife proper will be raised or lowered within the slot a', thereby increasing or decreasing as desired the depth of the channel produced in the leather being stitched. This is particularly useful where the leather, as sometimes, is of varying thickness, inasmuch as it provides a means for varying the depth of the channel in proportion thereto.

As at present constructed, the stationary cutters sometimes channel the leather too deep, thereby completely severing the leather at the thin places.

From the foregoing itl will be seen that I have produced an efficient and adjustable channeling mechanism which may be attached to any form of stitching machine and one which may be readily put out of commission without the necessity of stopping the machine or the removal of the cutter plate as is customary in the channel cutters as at present constructed.

Y It is apparent that many slight changes might be made without departing from the general scope of myI invention, therefore, I do not wish to be limited to the precise ,structure shown and described herein, but- I claim:

l. A channel cutter foi` stitching-machines comprising a base-plate, a rock-shaft j ournaled therein, a channel-cutter arranged at one end thereof, means arranged at the ends of the rock-shaft for adjusting it laterally of the base-plate, and horizontally-arranged adjusting means located at the opposite outer end of the rock-shaft for eecting the vertical adjustment of the channelcutter.

2. A channel cutter for stitching machines comprising a base plate, a rock shaft rotatably journaled therein, a channel cutter arranged at one end thereof, means for adjusting the rock shaft laterally of the base plate, a sliding block horizontally arranged upon said base plate, links connecting the block to the rotatable rockshaft, and means for imparting horizontal movement to the sliding block for effecting a vertical adjustment of the channel cutter.

3. A channel cutter for stitching machines comprising a base plate, a rock shaft j ournaled therein, a channel cutter arranged on one end ofsaid rock shaft, set screws arranged at either end of said rock shaft for adjusting the latter laterally of the base plate, a horizontally sliding block arranged upon said base plate, a rock arm attached to one end of said rock shaft, links connecting the rock arm to said sliding block, and means for adjusting the sliding block to effect a vertical movement of the said channel cutter. i

4. A channel cutter for stitching machines comprising a base plate, a rock shaft consisting of two members rotatably arranged upon said base plate, a cutter arranged'on one end of said rock shaft, means for laterally adjusting said rock shaft, and means for rocking said rock shaft thereby imparting a vertical movement to said channel cutter.

5. A channel cutter for stitching machines comprising a base plate, an elongated slot therein, a rock shaft journaled on the under side thereof, a channel cutter arranged on one end thereof adapted to be received within said elongated slot, means for adjusting the cutter laterally within said slot, a horizontal sliding block arranged upon said base plate, links and a rock arm connecting said rock shaft and sliding block together, and means for imparting a horizontal movement to the sliding block for effecting a vertical movement of the channel cutter. Y

6. A channel cutter for stitching machinescomprising a base plate, an elongated slot arranged transversely at one end, a rock shaft arranged longitudinally of said base plate, a channel cutter attached to one end thereof, a rock arm attached to the other end thereof, set screws engaging the outer ends of the rock shaft for adjusting the rock shaft laterally of the said base plate, a horizontal sliding block arranged transverselyI upon said base plate, links connecting the said rock arm and sliding block, and an adjusting screw journaled upon said base plate in engagement with the sliding block for imparting a horizontal movement, which in turn is adapted to raise and lower the said channel cutter.

VIn testimony whereof I afiX my signature.
